2007 Chevrolet Cobalt Sedan LT Engine won't Start

I have a 2007 Chevrolet Cobalt LT that won't start. When I try to start the car the engine will turn over but will not start. I thought it might be the battery but I cleaned the battery posts and made sure it was connected properly, but no luck on starting. Any Ideas?

I have a cobalt too and my car had done the same thing..wut my problem was that my fuse had blown out. look at ur fuse box and there should be one that would be for run or crank, check and make shure those arent blown and if not it may be ur fuel pump..ur car may not be getting enough fuel pressure for it to turn on.

I have had the same problem with my car. It is a Nissan, but it could be the same problem, and its easy enough to check yourself. On my car I will be driving and it will just cut out, then the engine turns but doesnt start, what it turned out to be was the screw inside the distributor cap coming loose and rattling around, once I put the screw back on it started right back up. If you have an owners manual to your car find the distributor cap and maybe check that. You will need a screwdriver most likely to get the cover off. Hope that solves the problem.

The most likely problem is a failed safety switch in the transmission. It will only allow the engine to turn over when in "neutral", or "Park". Next time it happens try moving the transmission selector through the full range of travel a couple of times. If this cures the problem, you may need new switch.

You're hydrolocked. Pull the sparkplugs out and crank the engine for 30-60 secs. there is a VERY GOOD CHANCE you could have done some major internal damage. Be prepared to replace your engine, but this might work.
